Reaction condition are presented that allow regioselective introduction (N9 versus N7) of guanine into sugar analogs under Vorbrüggen conditions. Using conditions, a set of N2-protected guanosine has been prepared with N2-isobutyryl-O6-[2-(p-nitrophenyl)ethyl]guanine (1) as nucleophile. This approach helps solve an important synthetic problem in the of guanosine analogs.
提出了允许在Vorbrüggen条件下将鸟嘌呤区域选择性引入鸟嘌呤(N 9对N 7)的反应条件。使用条件,已经制备了一组N 2-保护的鸟苷,其中N 2-异丁酰基-O 6- [2-(对硝基苯基)乙基]鸟嘌呤(1)为亲核试剂。这种方法有助于解决鸟苷类似物的一个重要的合成问题。
